Supersymmetric Janus solutions in ω-deformed N=8 gauged supergravity

We give a large class of supersymmetric Janus solutions in omega-deformed (dyonic) SO(8) maximal gauged supergravity with omega = pi/8. Unlike the purely electric counterpart, the dyonic SO(8) gauged supergravity exhibits a richer structure of AdS(4) vacua with N = 8, 2, 1, 1 supersymmetries and SO (8), U(3), G(2) and SU (3) symmetries, respectively. Similarly, domain walls interpolating among these critical points show a very rich structure as well. In this paper, we show that this gauged supergravity also accommodates a number of interesting supersymmetric Janus solutions in the form of AdS(3)-sliced domain walls asymptotically interpolating between the aforementioned AdS(4) geometries. These solutions could be holographically interpreted as two-dimensional conformal defects within the superconformal field theories (SCFTs) of ABJM type dual to the AdS(4) vacua. We also give a class of solutions interpolating among the SO(8), G(2) and U(3) AdS(4) vacua in the case of omega = 0 which have not previously appeared in the presently known Janus solutions of electric SO(8) gauged supergravity.

Automated summary

In this paper, a large class of supersymmetric Janus solutions in omega-deformed (dyonic) SO(8) maximal gauged supergravity with omega = pi/8 are presented. These solutions exhibit a rich structure of AdS(4) vacua with various symmetries and domain walls interpolating among them, providing insights into corresponding two-dimensional conformal defects in superconformal field theories (SCFTs) and unseen solutions interpolating among different AdS(4) vacua.
